An eye surgery system includes an operating microscope having at least one camera, a data memory, a pattern generator, and a display apparatus. The operating microscope presents a microscope image of an eye, and the at least one camera records a camera image of the eye. The data memory stores data that represent at least one predetermined position, relative to the eye, of a trocar to be inserted into the eye. The pattern generator generates a pattern representing the predetermined position of the trocar on the basis of the data stored in the data memory and the camera image recorded by the camera, and the display apparatus overlays the pattern produced by the pattern generator on the microscope image of the eye.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An eye surgery system comprising: an operating microscope configured to present a microscope image of an eye, the operating microscope including at least one camera configured to record a camera image of the eye; a data memory for storing data representing at least one predetermined position of a trocar to be inserted into the eye, the at least one predetermined position being determined relative to the eye; a pattern generator configured to generate a pattern representing the predetermined position of the trocar on the basis of the data stored in the data memory and the camera image recorded by the camera; and a display apparatus configured to overlay the pattern generated by the pattern generator on at least one of the microscope image of the eye or the camera image of the eye.
2. The eye surgery system according to claim 1 , further comprising an input apparatus for entering the data stored in the data memory.
3. The eye surgery system according to claim 1 , wherein the pattern generator is further configured to generate a pattern representing an outline of a limbus on the basis of the camera image recorded by the camera.
4. The eye surgery system according to claim 1 , wherein the trocar is substantially tubular.
5. The eye surgery system according to claim 1 , further comprising: a plurality of trocars, wherein the plurality of trocars have at least one of pairwise different dimensions from one another or pairwise different optically perceivable labels from one another, and wherein the plurality of trocars are provided for different applications.
6. The eye surgery system according to claim 5 , wherein the pairwise different optically perceivable labels from one another have different colors.
